Hunters are a special kind of people who dedicate themselves to the pursuit of treasures, magical beasts, and even other individuals. However, such endeavors require a license, and fewer than one in a hundred thousand can pass the rigorous qualification exam. Those who succeed gain access to restricted areas, amazing sources of information, and the right to call themselves Hunters.

As the Hunter elections reach a critical moment, Killua approaches the hospital where Gon lies in a coma. Can he and his frighteningly powerful sister Alluka reach Gon in time? If they succeed, Gon will have the chance to fulfill the dream that originally motivated him to become a Hunter: to reunite with his father, Ging.
